Feedback cooling of a levitated nanoparticle in a radially polarized vector beam trap
Felipe Almeida, M. Rademacher, J. M. H. Gosling +1
We demonstrate optical levitation and feedback cooling of a silica nanoparticle (radius = 78~nm) trapped within a radial vector beam (RVB) in high vacuum. Radial vector beams, when…
Feedback cooling scheme for an optically levitated oscillator with controlled cross-talk
J. M. H. Gosling, A. Pontin, F. Alder +3
Levitated optical mechanical systems have demonstrated excellent force and impulse sensitivity and are currently being developed for the creation of non-classical states of motion…
Optical centrifuge for nanoparticles
Peiyao Xiong, Kit Ka Kelvin Ho, J. M. H. Gosling +2
We study the creation of an optical centrifuge for the controlled rotation of levitated nanorotors within an optical tweezer. The optical centrifuge is created by rapidly rotating…
Sensing microscopic directional noise baths with an optically cooled and levitated nanoparticle
J. M. H. Gosling, A. Pontin, J. H. Iacoponi +2
Optomechanical devices are being harnessed as sensors of ultraweak forces for applications ranging from inertial sensing to the search for the elusive dark matter. For the latter,…
